abstract A seabed survey for the purpose of habitat identification and mapping at the North West of Jones Bank recommended Marine Conservation Zone (rMCZ) site, west of Cornwall, UK. A supplement to the main survey of the site conducted by Gardline in March 2012. The presnt survey, by cefas & the JNCC (July 2012) targeted some of the original ground-truth stations that had not previously been occupied and several additional stations. Ground-truth sampling by grabs and underwater cameras (video & stills images). Multibeam bathymetry and backscatter collected opportunistically on transit between stations. Broadscale habitat (BSH) and habitat FOCI (Features of Conservation Interest) recorded at time of sampling and included in cruise/survey report. More in-depth interpretation to be made in a Post-Survey Site Report, following integrated assessment of acoustics and outputs from laboratory analysis of benthic samples. These data are archived with the Marine Environmental Data and Information Network (MEDIN) Data Archive Centres (DACs) including the British Geological Survey (BGS) DAC for geology and geophysics, The Archive for Marine Species and Habitats Data (DASSH) and the United Kingdom Hydrographic Office (UKHO) bathymetry DAC. The full site data package including raw is also available on request from BGS.

additional_info Positions in Lat/Long WGS84 collected by Differential Global Positioning System (D-GPS). Multibeam bathymetry corrected to Chart Datum. Depths recorded for benthic sampling stations were read from ship's echo sounder. The survey collected data from Kongsberg EM2040 multibeam system to derive bathymetry and backscatter products. Acoustic acquisiton software = Kongsberg SIS. Processing software = Caris HIPS. Replacement Motion Reference Unit (MRU) fitted on 13 Feb 2012. Video capture by Kongsberg undewater camera with video and stills capability. Benthic sampling by 0.1 sq m Hamon Grab fitted with video camera. Sediment samples taken for particle size analysis (PSA). Faunal samples washed over 1 mm sieve and preserved in formalin for laboratory analysis. The survey targeted 12 locations in the rMCZ area, six of which were sampled by grab only, four by video only and two by both grab and video.
